Full-automatic tobacco leaf clamping and arranging picking vehicle

Abstract

The present application relates to the technical field of tobacco picking, more specifically to a full-automatic tobacco clamping and arranging picking vehicle. The full-automatic tobacco clamping and arranging picking vehicle is designed to solve the defects of the traditional picking method. The working principle is that after the picking worker picks up the tobacco, the tobacco is conveyed to the upper part by the conveying belt and falls into the temporary storage box. At this time, the baffle is opened by default, and the tobacco falls to the bottom of the tobacco compression device. The number of tobacco is determined by the gravity sensor. When the number of tobacco reaches a certain amount, the baffle is closed, and the tobacco clamping device works to efficiently compress and clamp the tobacco. The clamped tobacco clamp is transported to the tobacco clamp placing rack by the mechanical arm. In addition, the designed mechanism is relatively simple and low in cost, and the device parts can be easily replaced.

TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco leaf picking, more particularly to a full-automatic tobacco leaf clamping and arranging picking vehicle. BACKGROUND

[0002] With the continuous progress and innovation of modern agricultural technology, tobacco planting industry, especially in the application of automation and intelligent technology, has made remarkable achievements. However, although many links in the overall production process have been or are being transformed into mechanization and automation, the key link of tobacco picking still faces many challenges. Traditional tobacco picking operation almost completely relies on manual operation, which not only means that a large amount of labor resources need to be invested, but also workers are prone to physical fatigue after long-time repetitive and high-intensity work in the field, thereby affecting the picking efficiency. In addition, the manual picking method is difficult to match the speed of rapidly growing tobacco, resulting in a long picking period and low overall operation efficiency.

[0003] More importantly, due to the inevitable individual differences in manual picking process, such as different judgment standards and different handling methods, there are great differences in maturity, integrity and damage degree of the picked tobacco leaves, which directly affects the quality control of tobacco leaves in the subsequent processing process, and finally affects the taste and aroma of the finished product, reducing the overall quality and market competitiveness of tobacco leaves. At the same time, manual picking also faces the problem of rising labor costs year by year, which undoubtedly increases the economic burden of growers and limits the further expansion of the industry scale.

[0004] In summary, the traditional tobacco picking method has problems such as high labor intensity, low efficiency, and difficulty in guaranteeing the picking quality and consistency, which has become a bottleneck restricting the high-quality development of tobacco planting industry. Therefore, developing a new type of equipment that can efficiently, accurately and automatically complete the task of picking tobacco leaves not only can greatly improve the picking efficiency and reduce the labor intensity of farmers, but also can effectively guarantee the picking quality of tobacco leaves and promote the sustainable development of tobacco planting industry, which is the focus of attention and urgent need of the industry.
